Jowlawn 18 Ft Round Winter Pool Cover — Extra-Thick 185 GSM, 10-Year Weather-Resistant Shield

Jowlawn's 18 ft round winter pool cover is an extra-thick, reinforced winterizing kit designed to shield 18-foot above-ground pools from snow, ice, leaves, and UV with a durable 10-year performance expectation.

Built for homeowners who want a robust, season-to-season barrier, this upgraded Jowlawn winter cover combines heavy-duty construction with weather-resistant coatings and a complete fastening system. It’s designed to reduce debris entry, slow water degradation, and resist tearing under heavy loads so your pool requires less maintenance while closed for winter or long-term storage.

How does this cover resist tears and heavy weather?

The cover uses a 14×14 scrim weave and a dense 185 GSM body to deliver superior tear resistance compared with thin, single-layer alternatives. Reinforced seams and a double-layer waterproof shield add structural integrity, letting the cover hold up under snow weight and wind without splitting.

• 14×14 scrim count provides higher tear strength
• 185 GSM material density for durable thickness
• Reinforced seams to prevent separation at stress points
• Double-layer waterproof shield reduces moisture penetration

Will this cover protect water quality and block sunlight?

This model includes an LDPE coating engineered to block 99% of solar radiation, slowing algae growth and other sunlight-driven water changes. The blue top reflects heat to moderate temperature swings while the barrier keeps leaves and organic debris from introducing nutrients that degrade water.

• LDPE coating blocks most UV and solar radiation
• Blue reflective top reduces heat gain and temperature fluctuation
• Prevents leaves and debris from entering the pool water

How does the fastening system keep the cover secure in wind and snow?

Jowlawn supplies a steel-core cable with reinforced metal grommets spaced every two feet, enabling a tight, uniform tension around the pool rim. The included specially molded winch simplifies tightening so the cover stays snug and resists uplift from gusts or heavy snowfall.

• Steel-core cable resists stretching and snapping
• Metal grommets every 2 feet for even load distribution
• Specially molded winch makes tensioning fast and reliable
• Generous 4-foot overlap reduces gaps at the pool edge

Is this cover suitable for extreme temperatures and seasonal use?

The Jowlawn cover is rated to withstand temperatures from -10°F (-25°C) up to 180°F (80°C), making it durable in cold winters and warm transitional months. Its year-round versatility means you can use it for winterizing and as a seasonal shield when the pool is not in active use.

• Temperature tolerance from -10°F to 180°F
• Works for winter storage and seasonal protection
• Compatible with 18-foot diameter above-ground pools
• 4-foot overlap helps accommodate small size adjustments

Who is this for: The Jowlawn 18 ft round winter pool cover is aimed at above-ground pool owners who need a heavy-duty, low-maintenance solution for seasonal protection. It’s well suited for properties in snowy or windy climates, for anyone who prefers a long-lasting cover with secure hardware, and for users who want to reduce debris and UV exposure while the pool is closed.
